The ANOVA results showed that cultivar and maturity had a significant effect (p < 0.05) on all morphological characteristics studied, except for sphericity, H2, H3, and H4 where maturity was not statistically significant (p ≥ 0.05). The morphological parameters of RIT+ coconuts were statistically different from those of WAT+, PB113+ and PB121+ (p < 0.05). The WAT+ coconuts had high kernel thickness. The hybrid PB121+ was more spherical than other fruits and had a higher shell thickness. Improved Rennell Island Tall as a parent had good kernel water mass and large shape, while the improved West Tall Africa had good kernel thickness. Concerning PB113+ and PB121+ hybrids, they were similar in dimensional parameters. However, PB121+ fruits had the highest mass and volume, kernel mass, and shell mass compared to PB113+.

The genotypes were tested in a completely randomized design with three replications at a temperature of 28°C and a humidity of 65 to 70%.

The research was conducted in two agroecological zones (AEZ) within the state, employing a multi-stage sampling procedure to select 360 farmers for the study. Data analysis involved the use of means, frequencies, and multiple regression techniques. The results regarding adaptation practices in the respective AEZs revealed that in the Sudan AEZ, farmers primarily employed strategies such as multiple cropping (98.9%), early planting (63.9%), mulching/use of cover crops (36.1%), and increased fertilizer application (25.00%). In the Guinea AEZ, the most widely used adaptation strategies included multiple cropping (93.30%), utilization of new crop varieties tolerant to the evolving climate (72.20%), increased fertilizer application (47.20%), and the use of herbicides (25.00%). The production function analysis results demonstrated that approximately 85, 51, 53, 57, 81 and 65% of the variations in yields resulting from climate change adaptation strategies, such as the application of herbicides, utilization of organic manure, early planting, increased fertilizer application, mulching, and the use of cover crops, as well as the use of improved crop varieties tolerant to the new climate regime, were accounted for by the inputs. Furthermore, the coefficients of production inputs were significant and positively correlated with crop yields across different adaptation strategies and at various levels. In conclusion, the study found that farmers primarily employed technically-based adaptation strategies, and production inputs played a crucial role in determining crop yields across various adaptation approaches. It is recommended, among other measures, that adaptation materials be provided to farmers at a subsidized rate.

This study evaluated salinity tolerance of 72 lowland rice genotypes at the reproductive stage in field experiments conducted in coastal Marovoay, Madagascar. Field salinity levels were controlled at 2 and 4 dS m-1 through irrigation. Tolerance of selected genotypes was validated in pot experiments with salinity levels of 0, 4 and 8 dSm-1. Plant height, panicle number and length, panicle and spikelet fertility, straw weight and grain yield were measured together with visual scores of salt injury. Field salinity strongly reduced panicle number and spikelet fertility, reducing grain yield to 10 g m-2 in sensitive genotypes compared to 60 g m-2 in tolerant genotypes. Thus, 20% of genotypes were classified as tolerant, 50% as intermediate and 30% as sensitive to salinity. Four genotypes IR55179, MTM13_1, MTM13_3, MTM13_5, were confirmed as highly tolerant in the pot experiment. Higher spikelet and panicle fertility in tolerant genotypes contributed to their superior grain yield under salinity. These genotypes can serve as donors to improve grain yield of local varieties sensitive at the reproductive stage, possibly using spikelet and panicle fertility as selection criteria.

This study was carried out to assess the use of information communication technologies (ICTs) by farmers to access value chain information. ICTs application in cricket farming means ease to access cricket value chain information and improved interaction between cricket farmers and stakeholders. The study adopted an exploratory mixed method research design by use of a structured questionnaire and focus group discussions to collect data. The data was analyzed by using both descriptive and inferential statistics. Quantitative data was analyzed and interpreted using the R-statistical software. Qualitative data was analyzed thematically by drawing meanings from themes thereof. The results showed that the most sought information was cricket rearing practices and the least was market prices for cricket products. Radio was found to be the most significant ICT channel used (p?0.05). However, most farmers complained of poor infrastructure which made it difficult for them to utilize the ICTs effectively.

However, poor soil fertility is considered to be the major constraint for bean production in SSA. This study determines canopy spread, chlorophyll content, stomatal conductance, and seed yield of common beans in a field experiment conducted at Fumesua (rain-forest) and Akumadan (forest–savannah transition) agroecological zones. The study was conducted in the 2018 and 2019 cropping seasons using a split-plot arranged in a randomized complete block design with three replicates. The treatments consisted of the main plot factor namely varieties (Lv. “Semanhyia” and “Ennepa”) and the sub-plot factor P (75 kg ha−1), NPK (100 kg ha−1), ACARP organic fertilizer (4 t ha-1), ACARP plus NPK (2 t ha-1 + 50 kg ha-1), ACARP plus P (2 t ha-1 + 38 kg ha-1) and control (zero-amendments). Results showed that co-application of P, NPK, and ACARP fertilizer increased plant height and canopy spread by ≈9.54 and 11.25% compared with their sole application and the control, respectively. Similarly, the combined application of the organic and inorganic fertilizers increased chlorophyll content and stomatal conductance by 36.43 and 23.79% compared to their sole application and the control respectively. These observations translate into increased crop biomass and therefore seed  yield (≈ 42.54 - 46.58%). A significant variety and nutrient interaction were  observed in the number of pods per plant and seed yield, irrespective of the location. The results suggest that the growth and yield response of the crop may be optimized with the co-application of both P, and NPK with ACARP organic fertilizer.
